UO 638, Suplee Anticline (Permian of the United States)

Where: Crook County, Oregon (44.1° N, 119.7° W: paleocoordinates 18.3° N, 38.2° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Coyote Butte Formation, Kungurian (279.3 - 272.3 Ma)

• Mesogondolella idahoensis and N. pequopensis suggest Kungurian age (Wardlaw et al., 1982)

• group of beds-level stratigraphic resolution

Environment/lithology: marine; limestone

• Limestone lens; Sandstone beds are widespread but poorly exposed in the Coyote Butte Formation, limestone lenses are olive-grey, crinoidal fusulinid limestones in lower part of formation; Purer, finer-grained, deep-olive in colour and better bedded in the upper part with rarer fusulinids and common brachiopods.

Size class: macrofossils
